The TXS 0108E is a level shifter circuit, performing, in my project, a shift level voltage from 3.3V to 5V . Because of a design error in the wiring diagram, I left some pins with the same name on the connectors and their respective sides of the TXS 0108E IC. Not all pins, only 4. The result was that these 4 I/O pins now are connected in the pcb.
These interconnected pins are not required and are not used in the circuit, so that on both connectors, these pins will be left unconnected.
However, I can not predict if there is a problem in leaving the pins on the A and B side of the TXS0108E connected, and if this can interfere with other signals making noise or reducing the life time of the IC.
Does some one has any idea of what can happens ?
I noted that a current will flow from Vcca to Vccb once Vcca > Vccb. But, which kind of damage it can cause ?
